Dynamic Granular Messaging Persistence

1. A method for dynamic, granular messaging persistence in a messaging system, the method comprising: monitoring operational performance of a message broker; receiving a message for queuing in a message queue of the message broker; parsing the message to extract different fields and corresponding priorities, each of the priorities indicating a condition in which data in one of the different fields is to be persisted to fixed storage; selectively storing in the fixed storage, data for corresponding ones of the different fields based upon consideration of corresponding ones of the priorities extracted during parsing of the message and the monitored operational performance; and, queuing the message in the message queue.

2. The method of claim 1 , wherein the operational performance indicates a degree of resource utilization in a host server hosting the message broker.

3. The method of claim 2 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is to be persisted in the fixed storage in response to detecting a low degree of resource utilization, but that the data in the corresponding one of the fields is not to be persisted in the fixed storage in response to detecting a high degree of resource utilization.

4. The method of claim 2 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is to be persisted irrespective of a degree of utilization detected for the host server.

5. The method of claim 2 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is never to be persisted irrespective of a degree of utilization detected for the host server.

6. The method of claim 2 , wherein the resource utilization is processor utilization.

7. The method of claim 2 , wherein the resource utilization is message throughput in the message broker.

8. A message data processing system configured for dynamic, granular messaging persistence, the system comprising: a host server communicatively linked to client servers over a computer communications network and also fixed storage; a message broker executing in memory of the host server and brokering messages in a message queue for the client servers; and, a granular message persistence module coupled to the host server and comprising program code enabled to monitor operational performance of the message broker, parse a message received for queuing by the message broker in the message queue to extract different fields and corresponding priorities, each of the priorities indicating a condition in which data in one of the different fields is to be persisted to fixed storage, and selectively store in the fixed storage data for corresponding ones of the different fields based upon consideration of corresponding ones of the priorities extracted during parsing of the message and the monitored operational performance.

9. The system of claim 8 , wherein the operational performance indicates a degree of resource utilization in the host server hosting the message broker.

10. The system of claim 9 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is to be persisted in the fixed storage in response to detecting a low degree of resource utilization, but that the data in the corresponding one of the fields is not to be persisted in the fixed storage in response to detecting a high degree of resource utilization.

11. The system of claim 9 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is to be persisted irrespective of a degree of utilization detected for the host server.

12. The system of claim 9 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is never to be persisted irrespective of a degree of utilization detected for the host server.

13. The system of claim 9 , wherein the resource utilization is processor utilization.

14. The system of claim 9 , wherein the resource utilization is message throughput in the message broker.

15. A computer program product for dynamic, granular messaging persistence, the computer program product comprising: a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising: computer readable program code for monitoring operational performance of a message broker; computer readable program code for receiving a message for queuing in a message queue of the message broker; computer readable program code for parsing the message to extract different fields and corresponding priorities, each of the priorities indicating a condition in which data in one of the different fields is to be persisted to fixed storage; computer readable program code for selectively storing in the fixed storage, data for corresponding ones of the different fields based upon consideration of corresponding ones of the priorities extracted during parsing of the message and the monitored operational performance; and, computer readable program code for queuing the message in the message queue.

16. The computer program product of claim 15 , wherein the operational performance indicates a degree of resource utilization in a host server hosting the message broker.

17. The computer program product of claim 16 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is to be persisted in the fixed storage in response to detecting a low degree of resource utilization, but that the data in the corresponding one of the fields is not to be persisted in the fixed storage in response to detecting a high degree of resource utilization.

18. The computer program product of claim 16 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is to be persisted irrespective of a degree of utilization detected for the host server.

19. The computer program product of claim 16 , wherein at least one of the priorities indicates that data in a corresponding one of the fields is never to be persisted irrespective of a degree of utilization detected for the host server.

20. The computer program product of claim 16 , wherein the resource utilization is processor utilization.

21. The computer program product of claim 16 , wherein the resource utilization is message throughput in the message broker.
